BICYCLE.

SPECIFICATION forming part of Letters Patent N o. 612,393, dated October18, 1898.

Application led August 14,'1897. Serial No. 648,224. (No model.)

To Vif/ZZ whom it may concern:

Be it known that I, CHARLES S. BEEBE, a citizen of the United States,and a resident of Racine, in the county of Racine and State oflVisconsin, have invented certain new and useful Improvements inBicycles; and I do hereby declare that the following is a full, clear,and exact description thereof.

My invention has for its object to provide economicahstrong, and durablebicycles especially designed with reference to affording ease andcomfort to their riders when traveling on rough roads.

It therefore consists in certain peculiarities of construction andcombination of parts hereinafter set forth, with reference to theaccompanying drawings,and subsequently claimed.

Figure l of the drawings represents a side elevation ofthe greaterportion of a bicycle constructed according to inyinvention; Fig. 2, aView indicated by line 2 2 in the preceding figure, illustrating certainof the parts inverted and-in horizontal section; Fig. 3, a detail sideelevation, partly in section, illustrating a clamp connection thatconstitutes part of the improved bicycle; and Fig. 4, a detail plan viewillustrating a flexible strap-andbuckle connection that also constitutespart of said bicycle.

Referring by letter to the drawings, A represents a vertically-disposedmast joined at its lower end to a horizontal'crank-hanger B and havingits. upper end joined toa reach C, that is also joined to asteering-head D, in which the shank of a front fork E has its bearings.Another reach F is joined at its ends to the crank-hanger andsteering-head, and extending back from said crank-hanger are rear forksG,connected to braces H,hereinl the cantle of the bicycle-saddle, thepommel end of this saddle being in preferably adjustable flexibleconnection with the apex of the aforesaid frame, this apex being at thej unctionof the mast and rear-fork braces.

If the spring-bar I be of wood, the preferred clamp for its lower endcomprises a metal plate K in slip fit upon the front of mast A,pertaining to the pyramidal frame and provided with an upper hook-lug band lower eye-lugs c, another metal plate L, provided with innerstay-lugs d, embedded in said spring-bar, and a central outer lug e,having a transverse concavity, a bail M, engaging the concave lug andhaving screw-threaded ends extending through the aforesaid eyelugs, nutsf, run on said screw-threaded ends of the bail, and another bail N,supported by the aforesaid hook-lug and coupled at its ends to the bendsof the former bail.

The elevation of the saddle is determined by vertical adjustment of thecurved springbar, and adjustment of the flexible connection between themast member A of the frame and saddle determines the fore-and-aftadjustment of the latter.

The preferred connection between the pommel end of the saddle and apexof the frame is a strap P, provided with a buckle Q, intermediate of itsends, one end of said strap being herein shown looped on theshacklejoint bolt T and adj ustably engaged with the buckle.

Owing to the rigid connection of the springbar at its lower end with themast member of the frame and the curvature of said bar the latter willhave forward yield when the front wheel of the bicycle strikes anobstruction, and there is also up-and-down play of the aforesaid barwhen said bicycle is propelled over rough roads, these two motionsaffording ease and comfort to the rider. The backward yield of thespring-bar imparts tension to the flexible connection between Vthesaddle and mast member of the frame, thereby keeping said connectiontaut when the weight of a rider is not on said saddle.

The general design of the frame and other details may be somewhatmodified or changed from what is herein shown without departure from thegeneric scope of my invention.

Havingthus described my invention, what ICO ber thereof, arearwardly-extended yielding support in the form of a curved spring-barhaving its lower end in adjustable clamp connection with said mastadjacent to the crankhanger portion of said frame, a saddle connected iothe upper end of the yielding support, and a iiexible connection betweenthe a steeringhead, a reach connecting the upper end of the mast withthe steering-head, and another reach connecting said crankhanger andsteering-head, forks extending rearward from the aforesaid crank-hanger,and rear-fork braces in connection with said upper end of the mast; arearwardly-extended curved spring-bar having its lower end in adjustableclamp connection with said mast, a saddle connected to the upper end ofthe spring-bar, and a iiexible connection between the saddle and apex onthe frame at the junction of the aforesaid mast and rearfork braces.

5. A bicycle comprising a pyralnidal frame having a vertically-disposedmast as a niember thereof, a plate in slip iit with the front of themast and provided with an upper hooklug and lower eye-lugs, arearwardly-extended curved spring-bar provided at its lower end with arear plate having an outer lug, a bail supported on the latter lug andhaving saddle and apex of the aforesaid traine.

A bicycle comprising a pyramidal frame having a vertically-disposed mastas a inember thereof in rigid connection with the crankhanger, a curvedspring-bar having its lower end in clamp connection with the mast andits upper rear end divided and spread, a saddle having its cantle madefast on the upper rear branches of the spring-bar, a strap connected tothe poinxnel end of the saddle, and a buckle on the strap intermediateof its ends, one end of the strap being in looped connection with theapex of the frame and adj ustably engaged with the buckle. j

4. A bicycle having a frame comprising a crank-hanger, a verticallydisposed mast joined at its lower end to the crank-hanger,

screw-threaded ends run through the aforesaid eye-lugs, nuts run on saidends of the bail, another bail supported by the aforesaid hook-lug andcoupled at its en ds to the bends of the former bail, a saddle connectedto the upper end of the spring-bar, and a iiexible connection betweenthe saddle and apex of the frame.

In testimony that I claim the foregoing I have hereunto set iny hand, atRacine, in the county of Racine and State of Visconsin, in the presenceof two witnesses.

CHARLES S. BEEBE.
